CONSTRUCTION OF A 25 WATT CERAMIC BEAM POWER TETRODE
Abstract
Efforts were devoted to the development of a ceramic-metal tetrode featuring coaxial construction and an oxide coated cathode. T HE TUBES ARE DESIGNED TO DELIVER A MINIMUM OF THREE WATTS OF DRIVE POWER TO THE RCA-6884 over a frequency range of 30-76 mc with an input power of 50 milliwatts. The objectives were attained with the recently annou ced tube type RCA-7801, the specifications for which were rele sed in Janu ry 1961. Life expectancy of several thousand hours is indicated by the life test program. The 6.3 vol heater version of this type is recommended for all applications u ing the RCA-7801 and its associated circuitry. (Author)
